WATCH.

Application filed December 10, 1921. Serial No. 521,466.

To all whom it may concern.

Be it known that I, J AMES V. ORR, a subject of the King of GreatBritain, and resident of Monroe, in the county of Snohomish and State of\Vashington, have invented certain new and useful Improvements in\Vatches, of which the following is a speci iication.

This invention relates to watches and more particularly to the means forsetting the same.

Briefly stated, an important object of this invention to provide a watchhaving novel means whereby the second hand of the same may be set at sothat when the hour and. minute hands are set the second hand will be inexactly the right Starting position.

In carrying out the invention the second hand setting mechanism does notin any way interfere with the operation of the watch or place anexcessive strain on the same.

Further the invention aims to provide a watch having a second handsetting mechanism which is entirely automatic in its operation and whichis not easily rendered inoperative and further which does not in any wayinterfere with the time keeping qualities of the watch.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawing forming a part of this application and inwhich like numerals are employed to designate like parts throughout thesame,

Figure l is a plan view of the improved watch, parts being broken awayto illustrate the improved second setting mechanism.

Figure 2 is a plan view of the improved second hand setting mechanism,and the yoke associated with the same.

Figure 3 is a detailed sectional. view through the means for setting thesecond hand. the view illustrating the spindle oi the second hand andthe gear mounted there.- on. which gear forms a part of the ordinarywatch.

Figure 4; is a group view of the improved second hand setting mechanism.

In the drawing wherein for the purpose of illustration is shown apreferred embodiment of the invention, the numeral 5 generallydesignates a time piece having a mechanism 6, the said mechanism partlyconsisting of a yoke 7 rotatably supported as indicated at 8 and havingone end portion provided with a gear 9 which may be said to be thewinding gear and which is rotated for the purpose of winding the springof the watch. The winding gear 9 is constantly in mesh with gear 11having connection with a spur gear 12 operated by the usual stem 14.Vhen the yoke 7 is swung in a counterclockwise direction the windinggear 9 is engaged with the gear of the spring and when the yoke is swungin a clockwise direction the gear 9 is swung out of engagement with thegear ot. the winding mechanism, all of which is present in the standardwatch.

The other end portion of the yoke 7 is provided with a gear 14 adaptedto be swung in mesh with. the gear 16 of the hand setting mechanism. Asillustrated in Fig. 1 the gear 15 forming a part of the hand settingmechanism is operated in connection with a smaller gear 17 which is inturn connected to a relatively large gear 18 mounted on the shaft orspindle extending centrally through the watch and having connection withthe large and small hands.

The yoke 7 is operated by a setting lever 20 pivoted to the watchmechanism as indi rated at 21 and having a yoke contact branch 2 whichengages the laterally projecting lobe 24 formed at one end portion ofthe yoke. iVhen the finger piece 25 is drawn outwardly the yoke is swungon its pivot 8 so that the gear 15 is engaged with the hand settingmechanism so that the winding gear 9 is thrown out of mesh with the gearassociated with the spring of the watch.

The second hand is designated by the nu nieral 30 and is secured to ahollow spindle 90 mounted on a spindle 31 to which a small. pinion 33 isrigidly connected. As illustrated in Figures 2 and 4, a lever 34 whichmight be said to be a second hand setting lever pivoted intermediate itsends as indicated at 35 and. is provided with a p nion $36 mlapted to beswung into mesh with the pinion 3)) fixed on the spindle 31. A secondpinion 38 is. rotatably mounted upon the spindle 81. and is also engagedby the pinion 36 when the lever 34 is swung in a clockwise direction.\Vhen the lever 34- is swung in a clockwise direction and the gear 36 isswung into mesh with both of the pinions 33 and 38. the pinions 33 and38 being of a total thickness equal to the thickness of the gear 36.

A setting cam 39 is rigidly secured to the upper pinion 33 andwhen-swung about'the axis of the spindle 31 the cam causes the spindle90 to also move whereby the second hand 30 is swung to a predeterminedposition.

In other Words the spindle 31 whichis connected to the operatingmechanism of the watch positively rotates the gear 33 and the gear 33 inturn rotatesthe gear 36. Then the gear 36 is thus rotated the gear 33 isrotated and consequently thecam 39 rigidly secured thereto is alsorotated; It is important to note that the hollow spindle 90 to which thesecond hand is connected.

is'securely connected to the cam so that when sition by means-to belater described'the secondhand will also be swung to thepredeterminedposition. However, the cam 39 is swung to a predeterminedposition only when the lever 34 is swung on thepivot 35 and during. thismovement the gear 36 is outof engagement with the gears 33 and 33 andconsequently there is no driving connection between the spindle and thesecond hand.

When the lever 34 returns to its normal position as illustrated inFigure 2, the gear 36 is again engaged with the gears 33 and 38form-establishing the driving connection between the spindle and thesecond hand and it will be observed that the second. hand again beginsto turn" at exactly the right moment and in synchronism with the minutehand of the watch. That is to say, when the minute hand of the watch isset at the proper calibration on the dial ot the watch. and the memberE25 is moved inwardly the minute hand will begin to move the instant thedriving connection between the spindle and the second hand isreestablished.

With reference to Figures 3 and 4- it will be seen that the cam 39 isoperatively! con nected to thespindle 90 so that when a rotary'motion isimparted to the cam the second hand 30 willfbeibrought to apredetermined position which would most likely be fiO on the dial lotthe watch.

, Themeans for swinging the cam 39 to a predetermined positionconsistspartly of a secondhand settingarm or a-cam opera-ting arm curvedlongitudinally and having inner edgeiprovlded with span? of notches orrecesses 51 to receive the cheeks itormed o nopposite sides of aV'shaped recess 52 in tion where it is held by the arm 50 whichhas itsV-shaped projection 53 within the notch 52.

When the secondsetting lever 34 is swung in an anti-clockwisedirectionthe sprii'ig link 55 connected as indicated at 56 to the lever draws thearms 50 into engagement with the cam. spring link 55 is connected to theintermediate portion of the arm 50 as indicated at 57 and as the spring55 is lowered slightly,

a more or less yielding connection is provided between the second handsett-iuglever 34 and. the arm 50.

The second hand setting lever3 l-is automatically operated when the mainsetting lever is pulled out by a spring 60 having one tern'iinal portionreceived within a notch (53 in the forward portion of the lever 34. The

other terniinall portion o1"? the leaf spring 60 is bent upon itself andis secured to the watch mechanism as indicated/at 61. The spring 60normally acts to urge the second hand setting lever 34 in a clockwisedirection and when the pin dependingfrom' the projection 24 engages theintermediate por tion of the leaf spring. 60 the secondhand settinglever 34 is swung: in a counter clockwise direction, thereby swinl thearm to its operative position as Illustrated in l igure 21 In operationwhen the fingerpiece 25- is pulled outwardly the yoke is swung to aposition so that the rotation of the gear I l will turn the minute andhour hand and the movement of the yoke will swing the spring. 60 to thelett thereby causing the second hand operating lever 34; to move aboutits pivot 35. When th second hand setting lever a; arm is engaged withthe cam 39 so as to automatically position the second hand at 60577 ihen the setting lever ZOhas been drawn outwa y to thepositionillustrated in-Figs. ure 2 minute and hour hands maybe set and inwaimovement of thefinger piece -25 permits tl once.
